DETAILED DESCRIPTION
[0046]
[0047] Although the military vehicle 100 in the representations here is a tank, other land vehicles, such as off-road vehicles, or also watercraft or aircraft, such as ships or helicopters, which have a distance-active protection system 200, can also be equipped with a corresponding protection device 1.
[0048] The protection device 1 and the distance-active protection system 200 are components of a defense system 500. The defense system 500 serves, among other things, on the one hand to protect the vehicle 100 from possible approaching threats 400, in that the distance-active protection system 200 can shoot at and destroy them accordingly, and on the other hand to protect the vehicle 100 from repercussions R of the distance-active protection system 200 occurring as a result of the bombardment B of the threats 400.
[0049] The distance-active protection system 200 has a countermeasure 201, which is loaded by means of a loading device 202 of the protection system 200. The charges, in particular projectiles, projectile-forming charges or hollow body projectiles, of the countermeasure 201 are used to bombard B approaching threats 400, as shown schematically in
[0050] According to
[0051] The protective shield 2 is in an operating position according to the representation, so that it can protect the military vehicle 100 from possible repercussions R of the distance-active protection system 200. The protective shield 2 is set up in such a way that the area of the vehicle 100 is covered by the protective shield 2 starting from the countermeasure 201 to the middle of the vehicle 100, so that this area is protected accordingly against repercussions R of the distance-active protection system 200. While the protective shield 2 is arranged vertically in the operating position in this implementation, other orientations of the protective shield 2 in the operating position are also possible.
[0052] If, as
[0053] During the bombardment B by the countermeasure 201, however, repercussions R occur at the same time, such as in particular blasts or projectile residues, which act opposite to the direction of shelling and thus towards the vehicle 100. In order to protect the military vehicle 100 against these repercussions R, these are suitably absorbed by means of the protection device 1 and in particular its protective shield 2 and at least partially deflected, so that the vehicle 100 is correspondingly protected.
[0054] Outside of operations, the protective shield 2 may be in a parking position, as shown schematically in
[0055] In order to transfer the protective shield 2 from the operating position according to
[0056] When looking at the different positions of the protective shield 2 of
[0057] Various embodiments of the protection device 1 will be explained below in more detail on the basis of
[0058]
[0059] The protective shield 2 is designed at an angle in both a horizontal plane H and a vertical plane V. The angular design can advantageously cause repercussions R of a distance-active protection system 200 to be correspondingly deflected by the protective shield 2 and thus that the vehicle 100 can be protected, as is shown in
[0060] The protective shield 2 has a viewing window 4 for looking through it. The viewing window 4 may be particularly advantageous if the protective shield 2, for example, reduces the field of view of an optical arrangement and/or a crew member of the military vehicle 100. According to the embodiment the viewing window 4 is manufactured of bulletproof glass, so that in addition the area behind the viewing window 4 is also correspondingly protected against the repercussions of the distance-active protection system 200.
[0061] The viewing window 4 is arranged in front of a shield recess 2.1 of the protective shield 2 by means of a frame 5. For the arrangement, the viewing window 4 is positioned between the frame 5 and the protective shield 2 and in front of the shield recess 2.1 and is fixed by screwing the frame 5 to the protective shield 2 by means of multiple screws 6. Due to this arrangement, the viewing window 4 is replaceable and accordingly can be replaced if necessary, for example if it is damaged or the view is impeded.
[0062] In order to ensure the view through the viewing window 4 even in the event of vibrations occurring, which may occur in particular while driving the vehicle 100 or during use of the distance-active protection system 200, vibration protection which is not shown is provided in the frame 5. Especially if the viewing window 4 is made of bulletproof glass, vibrations can lead to reduced transparency if the viewing window 4 were also to vibrate. Furthermore, the vibration protection can prevent damage to the viewing window 4 due to occurring vibrations, which can occur, for example, when driving the military vehicle 100 or due to the distance-active protection system 200. In order to avoid the transmission of vibrations to the viewing window 4, the vibration protection can be designed as a damper.
[0063] For the movable attachment of the protective shield 2 to the military vehicle 100, the protection device 1 has the fastening device 3. The fastening device 3 allows the movement of the protective shield 2 between different positions, such as in particular between a parking position and an operating position.
[0064] The fastening device 3 has a carrier device 7, which carries the protective shield 2. The carrier device 7 is composed of four supports 7.1 which are vertical in the illustrations and two supports 7.2 which are horizontal in the illustrations, wherein the horizontal supports 7.2 are not formed contiguously, but are divided into multiple subsections. The supports 7.1, 7.2 are arranged in a lattice structure, running transversely. The supports 7.1, 7.2 are used to support the protective shield 2, in particular once repercussions R of the distance-active protection system 200 occur, wherein the lattice structure can cause an advantageous force application and force distribution in the supports 7.1, 7.2 or in the fastening device 3. However, different embodiments, in particular taking into account the intended use of the protection device 1, are also possible here. For example, the number of supports 7.1, 7.2 and/or the angles between the junctions of supports 7.1, 7.2 and/or the design of supports 7.1, 7.2 could be varied. Furthermore, it is also possible to design the supports 7.1, 7.2 not as part of the carrier device 7, but as separate components of the protection device 1.
[0065] The carrier device 7 also has a total of four stops 7.3, wherein a different number is also possible, which are designed as part of the vertical supports 7.1. By means of the stops 7.3, the carrier device 7 is connected to the protective shield 2. The connection is designed to be inseparable, for example by welding, but can alternatively be designed to be detachable, for example by screwing. The connection between the protective shield 2 and the carrier device 7 allows the at least partial introduction of the repercussions R from the protective shield 2 into the carrier device 7, in particular into the vertical supports 7.1, via the stops 7.3.
[0066] For the movement of the protective shield 2, the fastening device 3 has three hinges 8. The hinges 8 are attached to a first side of the protective shield 2 and can be attached on the opposite side to the military vehicle 100, so that the protective shield 2 can be moved, here pivoted, by means of the hinges 8. The movement of the hinges 8 takes place around an axis A, wherein the protective shield 2 is accordingly moved around this axis A. Since the axis A results from the arrangement of the hinges 8, a different arrangement of the hinges 8 from the exemplary embodiment, for example on the carrier device 7, is also possible. In particular, against the background of the available installation space for the protection device 1 on the vehicle 100, a differently oriented axis A may well be advantageous, for example if the protection device 1 and in particular its protective shield 2 must be pivoted past a body of the vehicle 100.
[0067] The protective shield 2 can be movably attached to the vehicle 100 by means of the fastening device 3 in that the carrier device 7 and the connected protective shield 2 are also moved when the hinges 8 move. For the implementation according to
[0068] As an alternative, it is also possible to arrange the hinges 8 not on the protective shield 2, but on the carrier device 7. In this case, when the carrier device 7 moves, the protective shield 2 would be moved if there is a fixed connection between the protective shield 2 and the carrier device 7.
[0069] The fastening device 3 also has two locking elements 9 for locking the protective shield 2 in different positions. According to the implementation, the locking elements 9 may be formed as captive screw bolts 9.1 or captive plug bolts 9.2.
[0070] The locking elements 9 allow the protective shield 2 to be immovably lockable in different positions relative to the vehicle 100. The distance-active protection system 200, in particular the countermeasure 201, can aim at an approaching threat 400, for example by a rotational movement, while the protective shield 2 remains unmoved in the respective position.
[0071] As a counterpart to the locking elements 9, the fastening device 3 has two locking holders 10. The locking holders 10 are essentially fork-shaped, wherein the first locking holder 10.1 has only one fork arm and the second locking holder 10.2 has two opposite fork arms. The fork arm of the first locking holder 10.1 has a threaded bore to accommodate the screw bolt 9.1, the fork arms of the second locking holder 10.2 each have a bore. To lock the protective shield 2 in one position, the locking elements 9 are inserted, in particular plugged or screwed, into the locking holders 10 according to the illustrations in
[0072] In
[0073] The protection device 1 according to
[0074] The protective shield 2 is also of an angular design in this implementation and has an angular viewing window 4 adapted to the protective shield 2. The surface of the viewing window 4 ends on one side at the surface of the protective shield 2. The angular design of the viewing window 4 may be particularly advantageous if a large area of the protective shield 2 is to be transparent, because, for example, the protective shield covers a large viewing area of an optical arrangement and/or of a crew member. Alternatively, however, it is also possible to design the viewing window 4 to be flat.
[0075] The protection device 1 also has a frame 5, which is arranged on the protective shield 2. The frame 5 is irreversibly connected to the protective shield 2, for example by welding, wherein it would also be conceivable here to alternatively provide a detachable connection, for example by screws. Frame 5 surrounds a shield recess 2.1, in which the viewing window 4 is fitted. In addition, it is possible that the viewing window 4 is clamped and/or glued into the shield recess 2.1. To simplify the installation of the viewing window 4 in the shield recess 2.1, the corners of the viewing window 4 can be beveled, for example, to allow a rear grip by a fitter during assembly.
[0076] The fastening device 3 has a carrier device 7, which has two vertical supports 7.1 and a horizontal support 7.2 in the illustration. The protective shield 2 is arranged on the carrier device 7 by means of stops 7.3, which are formed as part of the vertical supports 7.1.
[0077] The fastening device 3 also has two hinges 8, which are arranged on the protective shield 2. Alternatively, however, it would also be possible to arrange the hinges 8 on the carrier device 7. In this design according to
[0078] A difference of the protection device 1 according to
[0079] The locking elements 9 are used to lock the protective shield 2 and are designed as screw bolts 9.1. The screw bolts 9.1 connect the carrier device 7 to the locking holders 10. When moving the protective shield 2 from a first position, for example the operating position, to a second position, for example the parking position, the locking of the locking elements 9 is released, so that the locking holders 10 including the bridge 10.4 remain unmoved and fixed on the vehicle 100 and the carrier device 7 is moved with the hinges 8 and the protective shield 2.
[0080] According to
[0081]
[0082]
[0083] The protective shield 2 is held in the parking position by the fastening device 3, in particular by the carrier device 7, and is locked in this position by means of the locking elements 9. The protective shield 2 is at a distance from the roof of the vehicle 100, which avoids the transmission of vibrations to the protective shield 2 via the roof. However, it would also be conceivable to rest the protective shield 2 on the roof, so that locking it in at least in one position, in particular the parking position, would not be necessary.
[0084] The locking elements 9 are inserted into the locking holders 10. The screw bolt 9.1 is screwed to the first locking holder 10.1, the bolt 9.2 is plugged into the bores of the second locking holder 10.2. It is quite advantageous here that the locking elements 9 are secured by certain measures and are thus made captive, such as by a cotter or a locking ring or the preload of a spring.
[0085] In order to lock the protective shield 2 in the parking position, two parking brackets 11 are provided on the vehicle 100. During locking, the parking brackets 11 are received by the locking holders 10, so that when the locking elements 9 are inserted, they are simultaneously plugged through the parking brackets 11. The parking brackets 11 are therefore designed to correspond to the locking elements 9 and the locking holders 10 of the protection device 1.
[0086] For the design of the parking brackets 11 it is also referred to
[0087] The second parking bracket 11.2 is provided with a bore so that the bolt 9.2 is inserted through it when it is inserted into the locking holder 10.2. Movement of the protective shield 2 is thus prevented after locking due to the locking elements 9, so that it remains in the parking position.
[0088] When choosing the locking elements 9, further combinations of screw bolt 9.1 and bolt 9.2 are also possible. For example, two screw bolts 9.1 or two bolts 9. 2 can be used as locking elements 9. The combination of screw bolt 9.1 and bolt 9.2 implemented in
[0089] A sensor 15, which is not shown in detail, and which is designed as a position sensor and which is used to detect the different positions of the protective shield 2, is also arranged on the parking bracket 11.2. By using the sensor data, a coupling of the protection device 1 and the distance-active protection system 200 may be provided in such a way that the protection system 200, in particular the countermeasure 201, is accordingly only enabled in the operating position of the protective shield 2 and/or is accordingly blocked in the parking position of the protective shield 2. As a result, the protective effect of the protection device 1 can be additionally increased by avoiding repercussion effects R acting on the vehicle 100 while the protective shield 2 is in the parking position.
[0090] For coupling the protection device 1 and the distance-active protection system 200, the sensor data generated by the sensor 15 are transmitted to a control unit 16 which is not shown in detail, and which evaluates the sensor data accordingly and blocks or releases the distance-active protection system 200 on the basis of this sensor data. The coupling between the sensor 15 and the control unit 16 can be carried out by cable or alternatively wirelessly, in particular via a radio connection.
[0091] In this context, however, as an alternative to a separate control unit 16, it would also be possible to use an existing control unit 16 of the vehicle 100 and in particular of the distance-active protection system 200 to process the sensor data and to dispense with an additional control unit 16.
[0092] A possible arrangement of the control unit 16 is shown schematically in
[0093] To transfer the protective shield 2 from the parking position according to
[0094] For this purpose, the screw bolt 9.1 inserted in the locking holder 10.1 and the bolt 9.2 inserted in the locking holder 10.2 are loosened so that the locking holders 10 are released. In order not to lose them when loosening the locking elements 9, especially if the locking elements 9 remain partially in the locking holder 10, it is conceivable to make the locking elements 9 captive.
[0095] Once the locking elements 9 are loosened, the protective shield 2 can be moved by means of the fastening device 3, in particular by means of the hinges 8. In the exemplary embodiment, the protective shield 2 is pivoted here with the carrier device 7 by means of the hinges 8 which cannot be seen in these illustrations. The pivoting movement is carried out manually, for example by a crew member, wherein it is also possible to carry out the movement automatically, for example by a drive and/or hydraulics.
[0096] The movement of the protective shield 2 starts in the parking position according to
[0097] When the operating position according to
[0098] For this purpose, the first operational bracket 12.1 is provided with a bore through which the screw bolt 9.1 is inserted during locking. By screwing the screw bolt 9.1 to the locking holder 10.1, a connection, in this case a screw connection, is made between the locking holder 10.1 and the operational bracket 12.1 or the vehicle 100. With the screw connection, the aforementioned advantages arise in terms of vibration reduction.
[0099] The bolt 9.2 is inserted through the second operational bracket 12.2 into the locking holder 10.2. The operational bracket 12.2 also has a bore for this and can be designed similarly or identically to the first operational bracket 12.1.
[0100] In contrast to the parking brackets 11, the operational brackets 12 are of a more solid design, since when using a distance-active protection system 200, at least part of its repercussions R can also be transferred to the operational brackets 12 via the protective shield 2 and the carrier device 7.
[0101] In
[0102] In order to additionally support the protection device 1 in the operating position, the design according to
[0103] A fourth exemplary embodiment of a protection device 1 according to the invention is shown in
[0104]
[0105] In a difference from the previous designs, two hinges 8 are arranged directly on the protective shield 2 and thus allow a pivoting movement of the protective shield 2 around an axis A, which passes through the hinges 8. Since the pivot points of the hinges 8 are at different distances from the roof of the vehicle 100, the axis A is oriented at an angle relative to the roof of the vehicle 100. The orientation of the axis A results from the arrangement of the hinges 8 on the shield 2 and the vehicle 100. By an appropriate design and arrangement of the hinges 8, it is possible to adapt the orientation of the axis A, in particular to the installation space and/or the intended use of the protection device 1.
[0106] In order to carry the protective shield 2, the fastening device 3 of the protection device 1 also has a carrier device 7 in this design. The carrier device 7 is similar to the implementation according to
[0107] The fastening device 3 also has two locking elements 9 according to the type of the screw bolt 9.1 and two locking holders 10 connected via a bridge 10.4. In a difference from the previously described design according to
[0108] The locking holders 10 each have a bore for receiving the locking elements 9. In one of the bores, a sensor 15 is provided for detecting the different positions of the protective shield 2. This sensor 15 is designed as a switch in accordance with
[0109] Due to the design of the protection device 1 according to
[0110] Furthermore, only the locking of the protective shield 2 in the operating position, as shown in
[0111] For locking the protective shield 2 in the parking position according to
[0112] In the exemplary embodiment, in the parking position the distance between the protective shield 2 and the roof of the vehicle 100 is bridged by means of the locking connector 13. The locking connector 13 has a middle connector 13. 2, which can be adjusted in length by screwing in and out and at each end of which a holder 13.3 is arranged. Bolts 13.1 for locking the protective shield 2 are accommodated by means of the holders 13.3. The bolts 13.1 may be designed as simple plug-in bolts or as spring bolts, wherein a captive design is advantageous.
[0113] To lock the protective shield 2 in the parking position according to
[0114]
[0115] The carrier device 7 is connected to the locking holders 10 by means of the locking elements 9 in the operating position of the protective shield 2, so that occurring repercussions R of a distance-active protection system 200, which is not shown, are absorbed by the protective shield 2 and dissipated via the fastening device 3.
[0116] The locking connector 13 remains on the vehicle 100 in the operating position of the protective shield 2, wherein it is also conceivable to arrange the locking connector 13 or a part of the locking connector 13, in particular the bolt 13.1, on the protective shield 2 in the operating position.
[0117]
[0118] The protection device 1 shown in the upper part of the illustration corresponds to the design according to
[0119] The protection devices 1 and the distance-active protection systems 200 are components of a defense system 500 according to the invention. Here, the protection devices 1 are used to protect against repercussions R of the distance-active protection systems 200 and are therefore arranged on the vehicle 100 in such a way that they each lie on a line between the distance-active protection system 200 and the objects to be protected 300, in particular optics 301 and hatches 302, 303. It follows that the protective shields 2 of the protection devices 1 cover an area of the vehicle 100 which is protected from the repercussions R. In this context, it is conceivable to adapt the protective shield 2 to the available installation space on the vehicle 100. This adaptation can also be made directly in situ, for example by extending the protective shield 2 by welding and/or bolting on.
[0120] In this context, it is also possible that a defense system 500 according to the invention has only one protection device 1 and one distance-active protection system 200 or alternatively a plurality of these.
[0121] Furthermore, the protection devices 1 according to
[0122] The distance-active protection system 200 has a countermeasure 201 and a loading device 202, wherein the countermeasure 201 is rotatable. With an approaching threat 400, the countermeasure 201 turns towards the approaching threat 400 and shoots at it, causing repercussions R which act towards the vehicle 100. The repercussions R are absorbed and diverted by the protection devices 1, in particular their protective shield 2, so that the vehicle 100, in particular its objects which are to be protected 300, is protected.
[0123] In this context, it is also possible that the distance-active protection system 200 is coupled to the protection device 1 in such a way that the distance-active protection system 200 can only be used if the protective shield 2 is in the operating position. Thus, it could be prevented that repercussions R occur while the protective shield 2 is in the parking position by blocking the distance-active protection system 200 in the parking position and releasing it in the operating position.
[0124] Outside of operations, the protective shield 2 can be moved from the illustrated operating position to a parking position, which are shown in
[0125] To transfer the protective shields 2 from the operating position to the parking position shown, the countermeasure 201 of the distance-active protection system 200 is dismounted and the protective shield 2 is moved according to the previous description. According to
[0126] In the embodiments of the protection devices 1, it is provided that the movement into the different positions of the respective protective shield 2 is carried out manually by a crew member. It would also be conceivable here to provide a motor which moves the protective shield 2. The protective shields 2 are pivoted outwards relative to the vehicle 100 when moving from the operating position to the parking position, so that the contour of the vehicle 100 is reduced.
